что конкретно тебе нужно?
Вот пример с выполнением кода при получении сообщения "test"
Lua:
local ffi = require 'ffi'
local hook = {hooks = {}}
addEventHandler('onScriptTerminate', function(scr)
if scr == script.this then
for i, hook in ipairs(hook.hooks) do
if hook.status then
hook.stop()
end
end
end
end)
ffi.cdef [[
int VirtualProtect(void* lpAddress, unsigned long dwSize, unsigned long flNewProtect, unsigned long* lpflOldProtect);
]]
function hook.new(cast, callback, hook_addr, size)
local size = size or 5
local new_hook = {}
local detour_addr = tonumber(ffi.cast('intptr_t', ffi.cast('void*', ffi.cast(cast, callback))))
local void_addr = ffi.cast('void*', hook_addr)
local old_prot = ffi.new('unsigned long[1]')
local org_bytes = ffi.new('uint8_t[?]', size)
ffi.copy(org_bytes, void_addr, size)
local hook_bytes = ffi.new('uint8_t[?]', size, 0x90)
hook_bytes[0] = 0xE9
ffi.cast('uint32_t*', hook_bytes + 1)[0] = detour_addr - hook_addr - 5
new_hook.call = ffi.cast(cast, hook_addr)
new_hook.status = false
local function set_status(bool)
new_hook.status = bool
ffi.C.VirtualProtect(void_addr, size, 0x40, old_prot)
ffi.copy(void_addr, bool and hook_bytes or org_bytes, size)
ffi.C.VirtualProtect(void_addr, size, old_prot[0], old_prot)
end
new_hook.stop = function() set_status(false) end
new_hook.start = function() set_status(true) end
new_hook.start()

self.start()
return res

Добавь
Lua:
jit.off(callback, true)

В function hook.new(cast, callback, hook_addr, size)
Я в теме тоже обновил(и старой и новой)

Здрасте, продолжаем насиловать игру хуками, только уже виртуальных таблиц(обычный jmp hook - https://www.blast.hk/threads/39138/). Решил сделать либу, в которой этот и jmp хук, ее нужно кинуть в папку /moonloader/lib/ Затрагивая jmp hook, использование никак не изменилось, только пишем local...
